Comment 13 for bug 69163

Nah, it just was a quick and dirty hack: I hardcoded it in debian/rules

Besides, I had problems with kernel module too. The main problem probably probably is with my kernel (2.6.21-rc5). But there are packaging issues as well: "make-kpkg modules_image" didn't really work. The most obvious problem is that only root can write in /usr/src/modules/wacom.
The user I use for building only is the src group. This works fine with other stuff, like the nvidia module. (The nvidia package just provides a tarball. When unpacking the tarball, the directories inherit proper access rights for group src.)
